问题
I've already post about a problem wich brought me to this error, but I write it something more specific about the error :
When I use spellcheck.q in my query to define what will be "spellchecked", I always have this error, for every configuration I try :
java.lang.NullPointerException

All my other functions works great, this is the only thing wich doesn't work at all, just when i add "&spellcheck.q=my%20sentence" in the query...
Did anyone already have solved this problem ?
回答1:
It is fixed in trunk.
So get latest code from SVN or a nightly build.
